Abstract
A flat panel display comprising an aluminosilicate glass panel that exhibits a strain point higher than 640.degree. C., a weight loss less than 20 mg/cm.sup.2 after immersion for 24 hours in an aqueous 5% by weight HCl solution at 95.degree. C., a CTE in the range of 31-57.times.10.sup.-7 /.degree. C., is nominally free of alkali metal oxides and has a composition consisting essentially of, as calculated in percent by weight on an oxide basis, 49-67% SiO.sub.2, at least 6% Al.sub.2 O.sub.3, the Al.sub.2 O.sub.3 being 6-14% in conjunction with 55-67% SiO.sub.2 and 16-23% in conjunction with 49-58% SiO.sub.2, SiO.sub.2 +Al.sub.2 O.sub.3 >68%, 0-15% B.sub.2 O.sub.3, at least one alkaline earth metal oxide selected from the group consisting of, in the proportions indicated, 0-21% BaO, 0-15% SrO, 0-18% CaO, 0-8% MgO and 12-30% BaO+CaO+SrO+MgO.
